A Brief History
Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates three main physics principles: conservation of energy, conservation of momentum and friction via a series of swinging spheres.
Most people think that Isaac Newton invented the apparatus commonly called a Newton's Cradle, but he didn't. English actor Simon Preble invented the device in 1967 and named it in honor of Newton. In 1968 the first portable version hit the market and quickly gained popularity around the world as a fun, educational physics demonstrator.
